Polymarket - Issues with delayed open order read responses – Incident details

Trading has been reenabled.

We are currently in cancel-only mode. We will remain in cancel-only mode for at least 10 minutes before re-enabling trading.

The DB maintenance is in final stages. We will perform internal checks after and enter post-only mode shortly after.

The DB clean up is taking longer than initially estimated and trading will remain paused. We estimate another hour, but will update with a more concrete ETA as soon as we have it.

Trading will be paused at 01:30 UTC, Wednesday, September 2 for approximately 1.5 hour. We are working with AWS to apply a final fix to their internal DB issue for the root cause of the database replica lag which includes several database tuning operations. There will be a 5 minute cancel-only mode that will be announced before trading is resumed, and any changes in ETA will be announced as soon as we have them.

The restart has completed and we're monitoring the system. Trading has resumed and no degradation is currently present. We're continuing further tuning works in the background and will provide an update when available.

The restart is still in progress. We will provide and updates as soon as we have one.

We'll be performing an emergency CLOB maintenance on Tuesday, September 1 between 22:30 - 23:00 UTC to address the ongoing order issues due to database replica lag. During this period, there will be a brief restart with downtime of up to ~10 minutes. Order placement, cancels, and fills may be temporarily unavailable.
